Hi Alexander, I noticed that link as well. The link on the XG-2008 is blue. Also when i run -P 2 (dual streams) I get 9.8Gb/s (virtually 10GBe) so it must be a iperf3 / windows implementation similar to theirs. When i get around to it I will try a linux distro as it may be windows (SAMBA gets 700MB/s). Hope this helps others.

I don't think so. It is a 1920x on a x399 board. I will verify next reboot in case it set something weird. Additionally. I have switched it with an identical duplicate card and it still does this weird limit. Thanks for the suggestion

Has anyone got the AQtion 10G to transfer at full speed. I have the AQC107 in my unraid server and it seems to only connect /transfer at 600 to 700MB/s using iperf3. This is weird as it is not capped at 5GBps. I have tried different cables (CAT 6A) (3 cables - length as low as 0.5m) as well as Cat 5e/Cat 6 cables. They all seem to only connect above 5GBps. This is both direct link to another AQC107 (XG-C100C) or a onboard Gigabyte AQC107 (X399 Aorus Extreme) and via a XG-U2008 router [ 4] 0.00-1.00 sec 613 MBytes 5.14 Gbits/sec [ 4] 1.00-2.00 sec 615 MBytes 5.16 Gbits/sec [ 4] 2.00-3.00 sec 629 MBytes 5.27 Gbits/sec [ 4] 3.00-4.00 sec 638 MBytes 5.35 Gbits/sec [ 4] 4.00-5.00 sec 674 MBytes 5.65 Gbits/sec [ 4] 5.00-6.00 sec 656 MBytes 5.50 Gbits/sec [ 4] 6.00-7.00 sec 652 MBytes 5.48 Gbits/sec [ 4] 7.00-8.00 sec 641 MBytes 5.37 Gbits/sec [ 4] 8.00-9.00 sec 632 MBytes 5.31 Gbits/sec [ 4] 9.00-10.00 sec 640 MBytes 5.37 Gbits/sec It may be cables but they should down sync to 5000.
